Our old joomla installation which worked fine have been hacked. (version [url removed, login to view] stable)
Seems like the index files were overwritten.
I had a backup of both the [url removed, login to view] files for the frontpage and administration.
But on the top of the frontpage is now a upload form, which I don't how to remove.
[url removed, login to view]
I have an ftp access that I can give you. and login to administration.
